SELMER MODEL 300 ECHO UNIT (c1963-65)

SELMER 300 Mk 1 - COURTESY OF CHAMP ELECTRONICS (VALVE AMP REPAIRS), NOTTINGHAM, ENGLAND:

Valve Compliment is: 3 x ECC83; 1 x ECF82; "metal rectifier

SELMER 300 Mk 1A - COURTESY OF JASON HURLEY, LANCASHIRE, ENGLAND:

This particular unit has lost the perspex tape loop cover, which can be seen on the above example. It is however fitted with a tensioned pinchroller device which retains the tape to the motor drive and presumably regulates the motor speed better. The early Echo 300 above does not have this, and so it was presumably a later modification made by Selmer.

CROC-SKIN ECHO 300 Mk II - COURTESY OF MICHAEL KERR, UK:

Interestingly, the MkII has lost the tensioned pinch-roller that Selmer fitted on the later MkI version.
